262 ORCHIDACEM 



of P. Menzies, an early botanical collector. The specimens in 

 Lindley's herbarium are conspecific with those to which Hooker 

 gave the name Sjnranthes decipiens. 



E. DOLABRIPETALA sp. nov. Herba circa 3 dm. alta, a 

 rhizomate repente orta, supra folia approximata sericeo-pubescens. 

 Folia ad basim collecta, circa 4, lanceolata, 3-5 cm. longa, 1.4-2 

 cm. lata. Petiolus gracilis, 1 cm. longus a basi laminae ad basim 

 dilatatam vaginantem petioli. Bractece lineari-lanceolatae, acutae, 

 vaginantes. Bacemus 7 cm. longus, 2 cm. in diametro, laxiflorus. 

 Bractece injiorescentice lanceolatae, acuminata?, pubescentes, 4—7 

 mm. longae, inflmae ovario pubescenti aequilongae. Flores fere 5 

 mm. longi. Sepala lateralia ovato-lanceolata, acuta, 4.5 mm. 

 longa. Sepalum clorsale lateralibus multo angustius, aequilongum, 

 obtusum. Petala dolabriformia, 5 mm. longa. Ldbellum 4.5 mm. 

 longum, 2.5 mm. latum, ovato-lanceolatum, obtusum, subsaccatum, 

 processibus pluribus crasso-capillaribus. 



The nearest affinity of this species appears to be with E. striata 

 (Reichb. f.) A. A. Eaton, which has a more dense inflorescence, 

 different petals, broader labellum, and ovate-lanceolate leaves. 



Type (no. 233324 in U. S. Nat. Herb.) from near San Cristobal, 

 alt. 7000-8800 ft., Chiapas, Mexico, September 18, 1895, E. W. 

 Nelson (no. 3211). 



TROPIDIA Lindl. 



T. POLYSTACHYA (Sw.) comb, nov.; Serapias polystachya 

 Swartz Prodr. 119 (1788) ; Neottia polystachya Swartz Fl. Ind. 

 Occ. 3: 1415(1799); Chloidia vernalis Lindley ! Orch. PI. 484 

 (1840) ; Polystachya membrcmacea Richard Fl. Cub. Fanerog. 

 2:248 (1855), and Reichb. f. in Walp. Ann. 6: 644; Tropidia 

 Eatonii Ames Contr. Orch. Fl. Fla. 14, pi. 5 (1904). — Having 

 compared the material collected in Florida by A. A. Eaton with a 

 Jamaican specimen collected by Swartz, I find no adequate reason 

 for separating the Floridian from the West Indian plant.
